Accelerometer Data Collector

Overview
This app gathers accelerometer data, graphs it on the screen, and sends it over the network (local network or the Internet). Receiving the data is simple with the easy-to-understand Java-code that is provided below (see details section).

Send your iPhone OS device into the unknown and gather accelerometer data from a distance, or use it to monitor equipment/machinery.

Or if you are the programmer type, write a sweet computer game that uses your iPhone OS device as a remote control!

Features

Graphs accelerometer data to the screen
Sends accelerometer data over the network

Sends over local network or over the Internet
Uses TCP or UDP for data delivery

Adjustable sample rate: 0 to 60 Hz
Five data filters:

raw value
low-pass, adaptive low-pass
high-pass, adaptive high-pass

Has a built-in screen lock to disable screen input during data capture

Details
This app can send data over a TCP or UDP connection.

These example are free of charge and provide a framework for implementing your own awesome application that uses your iPhone's accelerometer.

Each sample of accelerometer data is sent over the network with the format:

   time   x y z

where 'time' is the timestamp, 'x' is the x-component of the device's acceleration, 'y' is the y-component, and 'z' is the z-component. All values are ASCII represented and separated by spaces. Samples are separated by the \n newline character.
